Dedicated Internet Access FAQs

  • Does your business need Dedicated Internet Access (DIA)?

    You need DIA if your business depends on consistent, high-performance internet for cloud platforms, real-time applications or critical operations. Unlike shared business broadband, which suffers from slowdowns at peak times, DIA is a dedicated, uncontended connection that keeps your services running smoothly. To explore if DIA is right for you, get in touch.

  • Is Dedicated Internet Access the same as a leased line?

    Yes, although strictly speaking, the terms have distinct meanings. DIA refers to a high-speed, private internet connection with guaranteed bandwidth, while a leased line is the dedicated, point-to-point physical circuit used to deliver DIA or other private network services.

  • How much does Dedicated Internet Access cost?

    The cost depends on factors like bandwidth, site location, access type and resilience requirements. You can get up-to-date pricing and compare options from leading UK providers using LIVEQUOTE, our free online pricing and ordering tool.

  • What bandwidths are available with DIA?

    DIA is scalable from 10Mbps up to 10Gbps, with symmetrical upload and download speeds. This allows you to match capacity to demand and scale easily as your business grows.

  • Can you scale up DIA bandwidth without installing a new circuit?

    Yes, you can usually increase bandwidth without replacing the physical circuit, as long as the underlying bearer has sufficient capacity. Bandwidth is upgraded by regrading the service, so you can scale quickly with minimal disruption.

  • What are DIA access tails?

    DIA access tails are the last‑mile connections that link your site to the Neos Networks backbone, determining how your service is delivered. Neos DIA offers a wide choice of providers, including BT Wholesale, Openreach, Virgin Media Business, PXC, Colt, Sky, CityFibre and Vorboss. So you can reach more locations, optimise cost and performance, and build resilience with diverse carriers. Get a quote with LIVEQUOTE.

  • What resilience options are available with DIA?

    DIA runs over our resilient MPLS core network with multiple peering providers, with optional RO2 (Resilience Option 2) and automatic failover for physical route diversity. DIA also offers tiered DDoS protection, providing real-time monitoring and automated mitigation against DDoS attacks.

  • How quickly can you install DIA?

    DIA is delivered via a dedicated leased line, so installation usually takes a few weeks depending on site location, existing infrastructure and service complexity. Where suitable fibre is already available, installation is often faster as less new infrastructure is required to connect your premises.

  • How do DIA and Managed DIA differ from IP Transit?

    DIA gives you a “wires-only” uncontended connection to the internet over a dedicated leased line, with your team responsible for the router and service configuration. Managed DIA (MDIA) delivers the same connection, but we take care of the hardware, monitoring and day-to-day operation with 24/7 support.

    Both are designed for businesses that want reliable, high-performance internet without the complexity of advanced routing.

    In contrast, IP Transit is designed for large organisations that want direct access to the internet backbone using BGP, with full control over routing.
